W - Waterproofing systems - Basement, tank, and area waterproofing

External basement waterproofing

Wet basements can not be fully used and might endanger the building substance. We offer different methods for making basements permanently waterproof: From the outside with polymer-modified thick film sealants, mineral sealing slurries or a cold self-adhesive waterproofing membrane – whereby the entire external wall area is treated and thus protected from water penetration. In repair cases, the external waterproofing can be installed even from the inside of the basement. This method is called “curtain injection”.

Internal basement waterproofing

In a repair situation, the basement can be waterproofed from the inside without excavating the soil around the building. This means that the basement is permanently waterproofed without the necessity of doing any sort of earthwork. This type of waterproofing is possible with the KÖSTER systems even when the wall has active leakages. Subsequently, a diffusion-open restoration plaster is applied after successful waterproofing.

Waterproofing balconies and terraces

This field poses the highest demands on waterproofing. It must be able to resist the weather, be waterproof and provide a certain structural stability. Also, outside the movements of the construction members are usually comparably large so that it is necessary to use waterproofing systems with high crack bridging capabilities.

Waterproofing tanks and pipes

Leaking sewage pipes in wastewater treatment plants lead to considerable damage which is often discovered very late. When restoring such damage it is important to mitigate the different types of damages with waterproofing systems which are specifically adapted to the need. The damage analysis reveals if locally limited waterproofing of the leakage is sufficient or if the entire area has to be protected from chemical attack.
